ROTATION TRANSMISSION MECHANISM PROVIDED WITH STRAIN-WAVE GEARING

摘要

The rotation transmission mechanism 1 which transmits the rotational driving force of the motor 2 to the load side member 5 via the speed reducer uses the wave gear device 3 as a speed reducer, and uses the wave gear device in the power transmission system ( The allowable load torque of the members other than 3) is larger than the predetermined upper limit load torque. The allowable load torque of the wave gear device 3 is defined by the ratcheting torque set to a value below the upper limit load torque. The wave gear device 3 functions as a mechanical fuse by ratcheting in an overload condition. The other power transmission member can be protected from an overload state without adding a separate member such as a torque limiter.
